Psychology of Addiction Collaborative

Advancing Substance Use Research, Training and Clinical Practice

The Psychology of Addiction Collaborative (PAC) is a group of researchers, educators, students and clinicians with a shared interest in substance use, addiction treatment, and health disparities. The PAC is based within the University of Houston’s Department of Psychological, Health, and Learning Sciences. Our current work focuses on:

  • Developing new and innovative approaches for reducing problematic substance use

  • Gaining a greater understanding of the factors that contribute to substance use and treatment outcomes.

Our past work has included studies on Latino smokers, opioid users, young adults who use marijuana and alcohol, HIV + smokers, and individuals in methadone maintenance treatment. The PAC aims to better understand the complex phenomenon of substance use and use that knowledge to inform the development of more effective and targeted interventions. Ultimately, the PAC’s mission is to disseminate interventions to the community and make a difference in the lives of those struggling with addiction.

It is by going down into the abyss that we recover the treasures of life.
Where you stumble, there lies your treasure.
